Latest review:
Source FM recently helped us fit out a new 8000 sq ft warehouse in Hackney. The project included installing new electricals, installing new fire and security alarms, repairing and repainting a heavily used concrete floor, redecorating, servicing the heating etc. The project had a very tight time frame and Source FM often had to work around members of our team as we started moving in while work was still ongoing. I'm pleased to say, all the work was completed in time and to a very high standard. We've since used Paul and Bill for a number of smaller projects, both at the warehouse and in our offices.

Conversions - General- 17 Mar 2019
Elliott has to be the best decorator/ builder I have used. On time with works and no lies or excuses!!! After posting my job he call me within 30 minutes to arrange a visit. This was the following day. When Elliott arrived he understood my requirements and saw my ideas and advised when he thought from his experience, would work better. He was very polite and professional. I needed the work done within 2 weeks due to carpet being laid. He completed the works within 7 working days. The works involved, Removing a wall, Removing all woodwork, Boxing out pipes, Plastering, New coving, New skirting, New architrave 2 doors, Building an under stair shelving unit, Moving a socket, sky cables, internet box, Removing radiator, Painting of all new plastered walls ceiling and woodwork to my chosen colours. I was even able to get him to squeeze in some additional works. This was creating shelves in my airing cupboard upstairs and boxing out pipes in my hallway. Elliott’s communication throughout the works was great. Even if he was unable to get round my house he would let me know at his earliest opportunity. Very very tidy during works. I have a 3 year old and Elliott made sure it was left safe every night. The finished works are to a high standard and he even popped back to do a bit off snagging on a Saturday morning. When I say snagging it was a few paint marks, re-laying my old carpet and dropping my keys off. I will be using Elliott in the future.

Architecture- 27 Nov 2017
I contacted Marius because he had good reviews and wanted someone reliable and capable so design a single story extension with large external and internal bifold doors. I wasn’t disappointed - Marius has been excellent throughout the whole design process and produced drawings to a high standard which met our requirements. Marius was an excellent communicator and always available to give advice when required. Further more, he went out of his way to contact local authorities regarding any questions I had at no extra cost to clarify any uncertainties. I would highly recommend his architectural services - he was good value and very professional.

What to ask a Balham extension builder before hiring?

Before hiring an extension builder in Balham or extension building company in Balham, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Balham?

An extension builder in Balham should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Balham extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Balham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Balham extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Balham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
